Remove the actual hash and just keep a linked list. Always move most
recently used entries to the front of the list, which also obsoletes
tracking the last used time stamp.

The GLib slice allocator has been obsoleted. Having a mixture of two
allocators can lead to hidden issues on systems that use different
implementations. Take the leap and replace everything with g_new/g_free.

This mode is only supposed to be used by cases when:
- in-dialog offerer doesn't have own MoH capabilities; and
- still want the recipient to hear the MoH music; hence
- an offerer checks whether a recipient is capable of MoH,
and launches a player based on given capabilities;
- the rest functions the same as with usual MoH hold;
Other information:
- `mode=reflect` is only to be used within dialog,
so, it's not meant for a session origination,
and hence stands alone from other MoH option flags
that actually give a metadata (e.g. blob data)
- `mode=reflect` hence contradicts with `mode=sendrecv`
which in its turn serves another purpose
Usage:
- `moh => { mode => 'reflect' }`

Switch from specialised handling of config sections (used to load
signalling templates) to a more general approach using a callback
mechanism. This allows us to add more information to the config file
while keeping the details of the underlying GKeyFile hidden. Use a typed
hash table for type safety.

Instead of lumping all strings of a file into a single hash function,
split them up into their respective sections, as there is no point in
matching against strings that aren't part of the switch statement. This
should give a bit of a performance boost.
Nested hash sections require special handling as the wrapper script
isn't smart enough to hande them automaticaly.

Change old code to directly return `str` objects instead of pointers to

Make `moh-max-duration` available for both
music-on-hold functionality as well as
for the media player.
For that to work, do the following:
- keep `moh-max-duration` config option only for MoH,
if not set (so 0) by default is 1800000ms (half an hour)
- for the play media functionality introduce flag option
`repeat-duration`, by default is disabled
Policy changes:
- duration counter can be used in common with repeats
counter, but then takes a precedence over it.
Hence if first a duration is underflown, then EOF triggered.
Otherwise if the duration counter is still positive, but
repeats are negative, then do EOF based on repeats.
- the repeats counter will always count down during each
iteration, even when used together with the duration counter
For MoH to survive, the repeats counter is simple set to 999
to let the duration counter always win over repeats one
- MoH cannot take duration disabled, since otherwise
would make no sense for it. Hence always takes internally
defined value 1800000ms (half an hour) if not defined
by the configuration option
Backwards compatibility:
- is kept in regards of repeats counter
- is kept in regards of the play media functionality

Sendrecv mode flag controls whether the sendrecv
state is forced to sendrecv, instead of the default
one sendonly, in the SDP body going towards recipient
(the one who will receive the MoH media).
Is declared as: moh=[mode=sendrecv]
Can be useful for corner cases, where the remote side
wants to see sendrecv state for whatever reason,
when getting MoH media and hence also remain in sendrecv
state in regards of the MoH originator.
Must be advertised once during the session origination,
nd then will affect the SDP body as soon as SDP sendonly
body is received (from the behalf of one, who advertised MoH
capabilities).
Backwards compatibility: doesn't affect non-MoH calls.
And doesn't affect offer/answer exchanges within MoH calls,
which do not put the remote side on hold.
Additionally: introduce a common function for the MoH flags
handling: `call_ml_moh_handle_flags()`, which does all
the required iterations/checks for the whole bunch of flags
at once.
Additionally: previously existing MoH tests adopted.
Additionally: new test introduced to check the SDP content,
when using mode sendrecv flag.
Remark: this flag is not mutually exclusive with
the zero-connection MoH flag.
Change-Id: I5bf6699f6890d8b927107cc143a18116efe45087
Zero-connection flag controls whether the connection
address offered in the SDP body going towards recipient
(the one who will receive the MoH media), is set
to all zeroes.
Is declared as: moh=[connection=zero]
Can be useful for older client implementations,
who want to see zeroed media when receiving sendonly
and getting put on hold.
Must be advertised once during the session origination,
and then will affect the SDP body as soon as SDP sendonly
body is received (from the behalf of one, who advertised MoH
capabilities).
SDP body recovers to the real IP addresses being inserted
into recipient's SDP, as soon as the media gets unheld.
Backwards compatibility: doesn't affect non-MoH calls.
And doesn't affect offer/answer exchanges within MoH calls,
which do not put the remote side on hold.
Additionally: previously existing MoH test adopted.
Additionally: new test introduced to check the SDP content,
when using zero-connection flag.

Add duration limit for the moh functionality.
This is required due to a possibility to get
monologues and hence packet streams stuck
forever and sending audio to recipients
which already don't exist.
A configuration option that controls that:
`moh-max-duration` - gets a value in milliseconds.
By default is set to 1800000 (half an hour).

Introduced Music on Hold functionality:
- available only for the offer/answer model,
no other scenarios (publish, subscriber etc.)
are covered with it
- it gets advertised always at the beginning of
the call (original offer/answer exchange)
- can be added for both sides: offerer/answerer
- the one who advertises its MoH capabilities
with its SDP offer or answer, can later trigger
MoH using sendonly SDP and unhold remote
party using sendrecv SDP
- MoH covers only audio type of media sessions
- there is no specific selection of media sections
to be held, thus, if one audio media puts the
call on hold, the whole call is held
- list of parameters to be given when advertising
MoH capabilities: a sound source (file, blob or db source);
sendonly/sendrecv hold; zero-connection hold;
At least an audio file source must be given
- MoH cannot be mixed with the play media functionality,
the last one triggered will override previous one
- MoH must be unheld to stop the media being sent
towards a recipient, otherwise only a termination
of monologues will stop this packets stream

Allow to-tag updates in answers only until a non-provisional response is
received. Add a flag to optionally suppress this feature.
Change-Id: I67110ede662f618ba5a355500d3d84050e6318cc
If we receive an answer from a to-tag that hasn't previously seen and no
corresponding monologue exists (created from a previous offer),
previously we would treat this is a separate and new call branch, create
a brand new monologue and dissociate the previous one. This may lead to
unexpected results as this new monologue has been created without the
same initialisation as was done for the original one, and so may be left
with incorrect or incomplete data (e.g. SRTP keys, codec information,
interface bindings, etc).
Improve this by treating an unexpected and unseen to-tag as an alias to
the already existing to-tag. Going forward both tags can be used
interchangeably to refer to the same monologue.
Add a flag to suppress this new behaviour, in case some situation is
made worse by it.

In order to be able to control, which media types
one wants to have in the call session,

Additionally, add according unit tests.
